When a Dunwoody police officer pulled over a driver and asked for his license, he did not anticipate that the man would hand him some beer.

But that’s exactly what police said Damon Tobias Exum did after striking Officer Alvin Rodriguez’s patrol car on I-285 westbound near North Peachtree Road just before 2:15 a.m. Saturday.

Rodriguez, who was not injured in the wreck, pursued Exum’s vehicle and stopped it, police spokesman Sgt. Fidel Espinoza said.

Exum, 37, of Dunwoody, was “heavily intoxicated” and “totally unaware that he had collided with the officer’s patrol car,” Espinoza said. He was arrested on eight misdemeanor charges, including DUI and reckless driving. It was Exum’s third DUI arrest, Espinoza said.

He is in the DeKalb County jail in lieu of $3,270 bond, according to online jail records.
